1. ABOUT THE GAME

  Introduction
  ------------

       After several years of absence, the legendary anime icon
  Astro Boy appears in this 2D sidescroller made by Hitmaker and
  Treasure. As expected from a Treasure co-developed product, the game 
  has easy-to-learn controls and gameplay, excellent graphics and
  sound, and high replay value. The game stages take on two forms -
  action and shooting. Other than punch and kick, Astro can also use
  his finger beam, arm cannon and the machine gun to defeat the bad
  guys during the action stages. As a bonus for the fans, several
  characters created by Osamu Tezuka also appear in the game. The
  characters will help Astro giving him power-ups and hints.



  Story Background
  ----------------

       In the near future, various robots were developed to help
  the humans. Among these robots is Astro, the first robot made with
  a 'soul'. With the guidance of Doctor O'Shay, Astro uses his
  abilities to rescue people from danger. Astro hopes to know the 
  secrets surrounding his identity while meeting other people.
  Unfortunately, the humans are already losing confidence with the
  robots. Disasters and mistakes are usually blamed on the robots.
  Although the future looks bleak, Astro doesn't lose hope. He still
  dreams of a world where humans and robots could co-exist peacefully.



======================================================================



2. GAME SYSTEM

  Menu Navigation
  ---------------

  Booting up the game:
       After turning on the power on your GameBoy Advance, you'll be
  able to select the language of the text display. You can change the
  language setting in the options menu later. The languages are:

       ENGLISH
       FRENCH
       ITALIAN
       GERMAN
       SPANISH
       JAPANESE



  Starting a new game:
       To start a new game, select an empty slot. Use the D-pad to
  enter your initials. Yes, you can use SEX and other similar words.
  After entering your name, the game will let you pick a difficulty
  setting.

       EASY
       NORMAL
       HARD

  I strongly recommend beginners to pick the easy difficulty first.
  Anyway, the obvious differences are:

       EASY
         a. You start with thirty EX/super points.
         b. The maximum EX point is 99.
         c. Enemies have regular speed, stun-recovery and attack power.
            As a reference:
            - 2,000 damage from a regular-sized "flunky" physical hit.
            - 1,000 damage from a regular-sized "flunky" projectile hit.
         d. The EX meter fills up even during an EX attack at
            a normal rate.

       NORMAL
         a. You start with five EX/super points.
         b. The maximum EX point is five.
         c. Enemies now move faster, stun-recovery improved, and doubled
            attack and defense ratings. As a reference:
            - 5,000 damage from a regular-sized "flunky" physical hit.
            - 3,000 damage from a regular-sized "flunky" projectile hit.
         d. Astro doesn't recover life points in some stages.
         e. Some enemies have a different attack pattern.
         f. Increase in number of enemies.
         g. The EX meter fills up even during an EX attack at 1/2 rate.

       HARD
         a. You start with three EX/super points.
         b. The maximum EX point is three.
         c. Enemies now move faster than before, stun-recovery improved,
            and quadrupled attack and defense ratings. Some bosses can kill
            Astro in one hit. As a reference:
            - 10,000 damage from a regular-sized "flunky" physical hit.
            - 6,000 damage from a regular-sized "flunky" projectile hit.
         d. Astro doesn't recover life points in some stages.
         e. Lower base score for Astro's attacks.
         f. Some enemies have a different attack pattern.
         g. Increase in number of enemies.
         h. The EX meter doesn't fill up during an EX attack.


  Copying a save game:
       Highlight COPY, select the data you want to copy,
       then pick an empty slot.


  Deleting a save game:
       Highlight DELETE and select the data you want to delete.



  PAUSE Menu:
       To access the PAUSE menu, press START during gameplay. You
  will be given several choices. They are:

       CONTINUE
       STAGE SELECT (!)
       RETRY
       EXIT

       CONTINUE is self-explanatory. The STAGE SELECT option is
  only available during the "Rebirth" play. This will bring you to
  the Stage Select screen. RETRY will bring you back to the start
  of the stage and will reset your score. EXIT will bring you back
  to the title screen.



  OPTIONS Menu:
       You can access the OPTIONS menu from the title screen. The
  available items are:

       TEZUKA/EXTENDED/ULTIMATE CHARACTER LIST
       HIGH SCORE
       SOUND TEST (!)
       EVENT TEST (!)
       LANGUAGE
       DELETE ALL DATA

       The character list will show the characters you have unlocked
  for the Omega Factor. Press left or right to scroll the available
  characters. Press up or down to view the different character
  drawings or portraits. Pessing 'A' will give you a description
  about that character. Initially, the character list is called "Tezuka
  Character List". After finishing the Rebirth part, it will now
  become the "Extended Character List". The extended list contains
  more information. You'll get the "Ultimate Character List" after
  finishing the game once on normal or hard difficulty.


  Selecting the high score option will bring you to a new menu.

       FROM BEGINNING
       STAGE
       BLOCK

       The "FROM BEGINNING" will record the best time and score you
  got for a particular difficulty level if you successfully finish a
  new game without any continues or retries. Unfortunately, this only
  records the time and scores for the 'Birth' part. The "STAGE" records
  the time and score for a particular stage. The "BLOCK" keeps track
  of the score and time for a particular block in a stage. The records
  for the block play are easier to beat when you already have the stage
  select option. You can check the records for the Birth-Rebirth play
  by pressing up or down.


       The sound and event tests are unlocked when you finish the
  game once. The sound test allows you to play the different BGM and
  sound effects used in the game. The event test lets you to view or
  watch events you have previously seen in the game. It will take a lot
  of replaying to get all the events because of the requirements.
  

       Stay away from the "DELETE ALL DATA" option. This will erase
  everything, including your high scores. The only use of this option
  is to remove your data if you're planning to sell your copy.



  Controls
  --------
  
  Punch       - Press the 'B' button. You can attack four times
                consecutively. The fourth attack becomes a kick.
                Punching is disabled during the shooting stages.

  Kick        - Press down+B. Regular enemies kicked by Astro are
                knocked back. Enemies in the path of the kicked
                enemy are also knocked away. Kicking is disabled
                during the shooting stages.

  Finger Beam - Press up+B. Astro's basic long range attack. During
                the shooting stages, the command for the finger beam
                is just the 'B' button.

  Arm Cannon  - Press the 'R' button. This uses up one EX/Super
                point. The arm cannon is Astro's strongest attack.
                It damages enemies and nullifies incoming projectile.
                When Astro is hit while performing the arm cannon,
                Astro will receive damage and the arm cannon attack
                will immediately stop. During the shooting stages,
                Astro can move while performing the arm cannon.

  Machine Gun - Press the 'L' button. This uses up one EX/Super
                point. The machine gun damages enemies and stuns
                them for a limited time. It also nullifies all enemy
                projectiles in the screen. During the shooting stages,
                Astro can move while performing the machine gun. Astro
                gains temporary invincibility during the attack.

  EX Dash     - Press A+B. This uses up one EX/Super point. You can
                direct Astro by pressing the D-pad while performing
                the EX Dash. Astro gains temporary invincibility
                during the attack.

  Jump        - Press the 'A' button. Jumping is disabled during the
                shooting stages.

  Jet         - Press the 'A' button while in the air. You can direct
                Astro by pressing the D-pad simultaneously with the
                'A' button. The number of times you can "jet" is
                determined by your jet level. Jetting allows you to
                go past enemies and projectiles. Take note that Astro
                is vulnerable during the initial animation when he is
                rotating. During the shooting stages, Astro can jet
                as many times as you want.

  Dash        - Press the direction pad left or right two times. You
                can also dash while in the air. Dashing also allows
                you to go past enemies and projectiles. For the sake
                of clarity, jet = dash.


  To skip the text or pause the game, press START.
  To fast forward the text or dialogue, press and hold SELECT.
  To view the Omega Factor, press SELECT.



  Score, Bonus, Multiplier and Combos
  -----------------------------------

       Each of Astro's attack has a base score. Check the "Power-Up"
  section for the different values. In order to get a better score,
  you need to use combos to increase the score multiplier. The score
  multiplier is located at the upper-right portion of the screen and
  the maximum value is 10. To combo, you must hit an opponent
  consecutively within a given time-frame. Astro is also allowed to
  cancel his moves just like in fighting games. Check the data below
  for the details. A "O" symbol indicates a possible follow-up and "-"
  means a follow-up is not possible.


               B     down+B     up+B     L     R     A+B     dash
  ------------------------------------------------------------------
    B          O        O         O      O     O      O        O
    Bx2        O        O         O      O     O      O        O
    Bx3        O        O         O      O     O      O        O
    Bx4        -        -         O      O     O      O        O
    down+B     -        -         O      O     O      O        O
    up+B       -        -         -      O     O      O        -
    L          -        -         -      -     -      -        -
    R          -        -         -      -     -      -        -
    A+B        -        -         -      -     -      -        -
  ------------------------------------------------------------------


       As you can see from the table, Astro can cancel most of his basic
  moves to his EX or super moves - arm cannon, machine gun and EX Dash.
  All of the EX moves are usually used as combo finishers. A dash cancel
  is needed to get a higher score multiplier. Please look at the following
  sample combos for a better explanation.

       Sample Combos:
            B, B, B, B
                 Astro's basic 4-hit combo.
                 Score multiplier: 4


            B, B, B, B, up+B, L/R/A+B
                 This combo is very similar to the first one.
                 Since the kick will send the enemy flying
                 towards the end of the screen, you can use
                 the finger beam to continue the combo. You
                 can then cancel it to one of your EX moves.
                 Score multiplier: 6


            B, L/R/A+B
                 This is the basic combo you can do during
                 the shooting stages.
                 Score multiplier: 2


            (B, jet) x n, L/R/A+B
                 A combo you can use during the shooting
                 stages. Make sure to press and hold down the
                 'B' button.
                 Score multiplier: 10


            B, B, B, dash, B, B, B, B, up+B, L/R/A+B
                 First sample combo that uses the dash. Take
                 note that you don't have to wait for the
                 dash animation to finish. Press the 'B'
                 button to stop the dash and continue with
                 the combo. As an insurance, use the machine
                 gun to stun your opponents first.
                 Score multiplier: 9


            (B, B, B, B, dash) x n, B, B, B, B, up+B, L/R/A+B 
                 A semi-infinite combo you can use against
                 some bosses. The combo is limited by the
                 number of dashes Astro can perform. Make sure
                 that the dash will bring you to the other
                 side of the boss.
                 Score multiplier: 10


             jump, B, B, B, B, up+a, B, B, B, B, up+B, L/R/A+B
                 A sample air combo that you can use against
                 some bosses like the Spider Robot. Take note
                 that the first attack should be made at the
                 peak of your jump. You might have some
                 difficulties performing the complete combo.
                 So, try skipping some of the attacks.
                 Score multiplier: 10


       Other than the score you get from defeating enemies, you also
  gain some special bonuses at the end of every stage. This bonuses
  will help you gain better scores. They are:

    Stage Clear Bonus    : Finish a stage without any retries.
                           Stage # x 5,000
       
    Time Bonus           : The faster you finish a stage, the higher
                           this becomes. This is based on a time limit
                           set by the game.

    Remaining Life Bonus : Remaining life of Astro / 2
                           The maximum life bonus is 50,000.

    Remaining EX Bonus   : Easy and Normal
                           Remaining EX point of Astro x 500

                           Hard
                           Remaining EX point x 25,000

    No Damage Bonus      : Finish a stage without getting hit.
                           You'll get 20,000 points.

    No EX Usage Bonus    : Finish a stage without using an EX move.
                           You'll get 25,000 points.


    During the game, you'll receive some bonus points when you get a
    heart when you have not received any damage.

         Small heart = 10,000
         Big heart   = 30,000


  Power-Up
  --------

       In order to power-up Astro in the game, he needs to encounter

  Omega Factor
  ------------

       The Omega Factor(Atom Heart in the Japanese version) shows

  requirements. Characters are placed in the Omega Factor depending
  on what Astro thinks about them -- evil, good, etc. Check the
  "Character List" section for more details. To view the Omega
  Factor, press SELECT during the game. A character must be "colored"
  to be considered unlocked in the character list. Sometimes,
  symbols will appear on some of the character faces.

             or more characters have already mentioned him or her.

             not be accessible after certain events. Check the

3. WALKTHROUGH

  Prologue (Stage 0-1 Science Ministry)
  --------
  Character: Dr. O'Shay

  WARNING!: Pressing 'START' anytime during this stage will end the
            tutorial. Check the "Events" section for additional info.

       The game starts off with a boy named Tobio who was involved
  in an accident. We then see a silhouette of a man who is at lost
  because of Tobio's death. When the "boy" wakes up, a scientist
  with a HUGE nose named Dr. O'Shay calls him Astro.

       Dr. O'Shay will give you a short training session about
  Astro's abilities. The training sessions are:

       a. movement     - Walk towards the right of the screen.
       b. jump and jet - Jump and jet over the wall.
       c. punch        - Press the B button at least once.
       d. finger beam  - Perform the finger beam by pressing up+B.
       e. kick         - Press down+B at least once.
       f. EX moves     - Perform any of the EX moves at least once.

       After the training, walk over to Dr. O'Shay and you will get him
  for the Omega Factor. Power-up any of Astro's abilities. After that,
  Dr. O'Shay will then give a short explanation regarding the Omega
  Factor and Astro's abilities. Wato, Dr. O'Shay's assistant, will be
  carried away by a group of enemies.



  Chapter 1 "Metro City"
  ---------
  Summary: Rescue Wato and find out the true purpose of the enemy.

       Stage 1-1 Metro City
       ---------

            The stage starts with Astro in Metro City. Upon landing,
       Astro will see the bad guys leave the screen with Chiyoko.
       Take note that these bad guys are the generic enemy fodder.


            This is a straightforward stage. To advance, you need to
       defeat the wave of enemies that will appear in the screen. At
       the first screen, you can break the glass at the background
       to get additional points. At the end of the stage, Astro can
       collect a heart that will recover lost life points. A small
       heart recovers 30,000 life points. In case you have a full life
       meter, you'll get 10,000 points. Hearts also add to your EX
       stock. This is especially useful in hard difficulty. A small
       heart gives 3 EX points.
